I have had a Hi-Z four square up since early 2012. It is a very good system for
my needs. I have adequate land - although it was necessary to put it out in the
front yard to get it away from the TX antenna - for the 80 foot per side
layout. I see 18 to 24 db front to rear rejection depending upon angle of
signal arrival. My system is probably compromised by power lines that border
two sides of my property. The Hi-Z is connected to the second RX in my K3 and
is used in diversity mode on 160 and 80.
For main RX on the low bands I used to have two, 450 foot reversible beverages.
However local noise sources have made those beverages almost unusable in the
past 5 years. Hence I was forced to put up antennas which have excellent rear
rejection. For that purpose, I installed three "dual flag" receive arrays.
These are similar to DHDL rx antennas developed by George, AA7JV except that I
use two flag loops instead of the half deltas.
The flag antennas (really simplified Waller flags) have excellent rear
rejection and make the AC power line noise almost non-existent. If you purchase
the Bev-Flex, I do recommend installing it as a EWE or FLAG. If you go with the
Hi-Z two element, make sure there are no antennas or large metal objects in
near by proximity or you won't get the receiving pattern you need.
